A pregnant woman was stopped from crossing a Los Angeles street Wednesday afternoon because the road was closed for President Barack Obama’s motorcade.

NBC4 anchor/reporter Robert Kovacik witnessed the woman take shelter at a bus stop bench on the south side of Third Street east of Robertson Boulevard and across from Cedars-Sinai Medical Center.

The pregnant woman was with her spouse at the time. Witnesses and two LAPD officers on scene said they believe the woman was in labor and told NBC4 an ambulance was called to the location as a precaution.

NBC4 talked to the woman on the scene, and she asked not to be shown on camera. She was out of breath and appeared to be in active labor.

Police on the scene tell NBC4 there were two medical emergencies during the president’s motorcade, the woman’s pregnancy and a man having post-surgical problems.

Kovacik shot video on his cellphone of the woman sitting at a bus stop bench and posted it to his Instagram account.

"As soon as we can, looks like the motorcade is coming through right about now," the LAPD officer responded. "We’ll be able to open it up for traffic and first we’ll thing we’ll try to get to will be an ambulance, but I can’t guarantee ... the time on that," the officer said.

Obama was in Los Angeles Wednesday afternoon for a 24-hour visit that included two political fundraisers and a speech at Los Angeles Trade-Technical College. Wednesday's fundraisers included a stop at the Hancock Park home of television producer Shonda Rhimes.

According to witness Carrie Clifford, the woman waited at least 30 minutes before she could cross the street, she told The Blaze. Clifford tweeted updates and pictures from the location, including: "Ironically, Obama is going to @shondarhimes. This could be #GreysAnatomy - woman in labor can't get to Cedars cuz of O."

The White House has not responded to a request for comment. A spokesman for the Secret Service said the incident is under investigation by the LAPD.

"The Secret Service works closely with state and local police counterparts in planning for and conducting motorcade movements of our protectees," Secret Service spokesman Brian Leary said in an email. "It is always our policy to prepare for and facilitate medical emergencies, medical flights, ambulances etc. in the fastest and safest way possible."
